SEAL-LOCK.

' SPECIFICATION forming part of Letters Application filed September 15),1883. (Model.)

To aZZ whom it may 41m Be it known thatIfiOHAnLns A. Jnwnrr,

acitizen of the United States, residing at Mar shalltown, in the countyof Marshall and State of Iowa, have invented certain new andusefulImprovements in Seal-Locks for Freight-Oars; and I do hereby declare thefollowing to be a full, clear, and exact descriptionof the invention,such as will enable others skilledi'n the art to which it app'ertains tomake and use the same, reference being had to the accompanying drawings,and toletters or. figures of reference marked thereon, which form a partof this specification. i

Figure l is a perspective view, showing the application of my inventionto a freight-car. Fig. 2 is a section taken horizontally through Fig. 3on line 00 00. Fig. 3 is a front view of the seal lock. Fig. 4 is afront view of the showing the seal.

same parts with the face of the lock removed, Fig. 5 is a section takenvertically andtransvers ely through the lock in plane m m, Fig. 6,showing the seal therein.

Fig. 6 is a vertical longitudinal section through the lock with thesealfast therein. Fig. 7 is a perspective view of the seal.

- This invention relates to seal-locks and seals for freight-ears; andit consists in certain novel improvements on seal-locks and sealstherefor,which will be fully understood from the followingdescription,when taken in connection with the annexed drawings.

A designates the frame or box of the scal a lock, which is constructedwith a flange, a,

having an eye through it to receive a bolt that secures the box to thedoor of a car. This box is also constructed with a right-angular flange,

a, that fits against the end of the door, and also with a passage, 1),for the hasp or bolt B,

and a passage, 0, for the padlock-latch C. The hasp or bolt B is pivotedto a guide, D, which is bolted to the car-body, and this hasp is constructed with an engaging-hook, d, a groove,

01, horizontal and vertical shoulders 0F, and two vertical jaws, (Z d,which form a vertical groove to receive the narrow neck of a seal, asshown in Fig. 2 of the drawings. The pad- Patent N0. 29 1,352, datedJanuary 1, 1884.

. l having aholethrough it for receiving the link 1 .of a padlock. Thisenlarged end of the latch may also be provided with holes for receivingthe well-known wire seals, or other kinds of seals. On the left-handside ofsaid latch is a shoulder, e, which prevents itfroin being drawnout of the box or frame A when the face-plate is secured to the latter.

- E designates a drop-catch, which has a beveled nose, f, adapted toenter the groove cl in the top of the hasp or bolt B, and which isallowed to receive free vertical play between the rightis formed 011 theface-plate of the box. This the padlock-latch G, and forms the insideguide for the said parts. The drop-latch is constructed with twoshoulders, which rest on lugs formed, respectively, on the back and faceplates of the box A, when the hasp or bolt B is out of this box. Whenthe hasp or bolt B is latched in this box,the beveled nose of thedrop-catch E is received in the groove d. That portion of the inner sideof the face-plate of the box or frame A which lies over the jaws d (2when the hasp is latched in place is recessed, as shown at h, Fig. 5,for the purpose of receiving said jaws d" (P, with the seal held betweenthem.

The seal which I have invented and adapted to the lock consists of athin piece of metal, having a tag, H, on which may be printed anydesired characters, a head, H, through which shown by Fig. 5 of thedrawings.

Before closing the car-do0r, the seal is applied to the hasp or bolt bybending the perforated head H at right angles to the neck H andadjusting this neck in the groove between the jaws (1 d The perforationthrough the head H 'will now lie directly over the groove d in the topof the hasp. hen the door is shut, the hasp will be caught and held bythe gravitating padlock-latch O, and the nose of the catch E will dropthrough the hole in the head of the seal. The latch G is then locked bythe well-known padlock, and the oar-door is secure.

It will be observed that the door cannot be opened without breaking theneck of the seal from the perforated head thereof, which is securelyheld by the drop-catch E.

hand side of the box A and a partition, g, which partition lies betweenthe drop-catch E and It will also be observed that the latch or lock isproof against snow and sleet, and that it is not liable to derangementeven when sub jected to rough use. It is also automatic, both 5 inlatching the hasp and in securing the seal in its place.

One great advantage attending my lock is that the upper portion of thegravitating latch G is wholly inclosed within the lock-case;

IO also, that this latch has horizontal notch or passage 0, the upperwall of which is beveled.- This notch or passage receives the neck ofthe bolt B, and securely holds it when the hook of the bolt is held bythe nose 6.

I 5 \Vhile my device is especially useful for locking and sealing thesliding doors of boX or freight cars, I contemplate its use for lookingdoors or sliding shutters wherever they may be applied. The lip p, whichis shown in Figs. 1 and 2 of the drawings on the faceplate of thelock-case, is undercut to form a safety-shoulder, against which theshoulder d on the bolt abuts when the latter is in the case. The objectof this lip 19 is to effectu- 2 5 ally prevent the introduction of athin metal plate or other instrument into the lock-case, with the objectof maliciously unlocking the bolt.

What I claim as new, and desire to secure 30 by Letters Patent, is-

1. The combination with the lock-case having a vertical opening throughits bottom and a horizontal hole through one end, of a hookednose bolt,13, and a gravitating latch, O, having a horizontal notch, a bevelednose, and a 5 lower perforated extension, the upper portion of saidlatch beingwholly inclosed in the lockcase, substantially as described.

2. A bolt, B, grooved at d, and having a hooked engaging end and jaws (1the latter forming a vertical groove for the neck of the seal, incombination with the drop-catch E, substantially as described.

3. The combination of the box A, the latch O, the hasp-bolt B, havingjaws d, which form 5 a groove to receive the neck of the seal, and thedropcatch E, substantially as described.

4. In a seal-lock case having a lip, 1), undercut, a hooked bolt havinga shoulder, (P, a drop-catch, O, and a gravitating latch, E,substantially as described. o

5. The combination of a look-case, a beveled latch, E, a bolt grooved-atd, and provided with jaws d, forming a vertical groove, and a bent taghaving a perforation through its head, 5 5

substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
